Migration guide: use `return` outside of `try` blocks and `return await` inside `try` blocks. Signed-off-by: Miroslav Bajtoš * **eslint-config:** the `@typescript-eslint/prefer-nullish-coalescing` rule prefers nullish coalescing, for example, `ttl ?? 5000` over `ttl || 5000`. See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#nullish-coalescing * **eslint-config:** the `@typescript-eslint/prefer-optional-chain` rule will report violations if optional chaining is not used. For example, it prefers `options?.ttl` over `options && options.ttl`. See https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#optional-chaining ## [4.1.5](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.1.4...@loopback/eslint-config@4.1.5) (2019-11-25) **Note:** Version bump only for package @loopback/eslint-config ## [4.1.4](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.1.3...@loopback/eslint-config@4.1.4) (2019-11-12) **Note:** Version bump only for package @loopback/eslint-config ## [4.1.3](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.1.2...@loopback/eslint-config@4.1.3) (2019-10-24) **Note:** Version bump only for package @loopback/eslint-config ## [4.1.2](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.1.1...@loopback/eslint-config@4.1.2) (2019-10-07) **Note:** Version bump only for package @loopback/eslint-config ## [4.1.1](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.1.0...@loopback/eslint-config@4.1.1) (2019-09-27) **Note:** Version bump only for package @loopback/eslint-config # [4.1.0](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.0.2...@loopback/eslint-config@4.1.0) (2019-09-17) ### Features * **eslint-config:** enable "no-misused-promises" rule ([88d5494](https://github.com/strongloop/loopback-next/commit/88d5494)) ## [4.0.2](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.0.1...@loopback/eslint-config@4.0.2) (2019-09-03) **Note:** Version bump only for package @loopback/eslint-config ## [4.0.1](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@4.0.0...@loopback/eslint-config@4.0.1) (2019-08-19) **Note:** Version bump only for package @loopback/eslint-config # [4.0.0](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@3.0.0...@loopback/eslint-config@4.0.0) (2019-08-15) ### Features * **eslint-config:** upgrade to @typescript-eslint/eslint-plugin 2.0.0 ([1ec5b2f](https://github.com/strongloop/loopback-next/commit/1ec5b2f)) ### BREAKING CHANGES * **eslint-config:** @typescript-eslint/parser and @typescript-eslint/eslint-plugin 2.0.0 may have introduced breaking changes for recommended rules and configuration # [3.0.0](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@2.0.2...@loopback/eslint-config@3.0.0) (2019-07-31) ### Features * **eslint-config:** enable "no-return-await" rule ([e28a3c3](https://github.com/strongloop/loopback-next/commit/e28a3c3)) ### BREAKING CHANGES * **eslint-config:** "return await" is no longer allowed, just return the promise without awaiting its resolution. ## [2.0.2](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@2.0.1...@loopback/eslint-config@2.0.2) (2019-07-26) **Note:** Version bump only for package @loopback/eslint-config ## [2.0.1](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@2.0.0...@loopback/eslint-config@2.0.1) (2019-07-17) **Note:** Version bump only for package @loopback/eslint-config # [2.0.0](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@1.1.2...@loopback/eslint-config@2.0.0) (2019-06-28) ### Features * **eslint-config:** enable "no-floating-promises" rule ([256e3e8](https://github.com/strongloop/loopback-next/commit/256e3e8)) * **eslint-config:** upgrade eslint to v6 ([b52a40c](https://github.com/strongloop/loopback-next/commit/b52a40c)) ### BREAKING CHANGES * **eslint-config:** We require eslint version 6.0 as a peer dependency now. To upgrade your project using our eslint-config, bump up eslint version in your package.json file to "^6.0.0". The new eslint version added new recommended rules, most notably "require-atomic-updates" and "no-prototype-builtins". You may get new linting errors after upgrade, fix them by changing your code or adding eslint-ignore comments as needed. ## [1.1.2](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@1.1.1...@loopback/eslint-config@1.1.2) (2019-06-17) **Note:** Version bump only for package @loopback/eslint-config ## [1.1.1](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@1.1.0...@loopback/eslint-config@1.1.1) (2019-06-06) **Note:** Version bump only for package @loopback/eslint-config # [1.1.0](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@1.0.0-3...@loopback/eslint-config@1.1.0) (2019-06-03) ### Features * replace tslint with eslint ([44185a7](https://github.com/strongloop/loopback-next/commit/44185a7)) * **eslint-config:** allow detection of tsconfig file ([5c16db6](https://github.com/strongloop/loopback-next/commit/5c16db6)) # [1.0.0-3](https://github.com/strongloop/loopback-next/compare/@loopback/eslint-config@1.0.0-2...@loopback/eslint-config@1.0.0-3) (2019-05-31) **Note:** Version bump only for package @loopback/eslint-config # 1.0.0-2 (2019-05-30) ### Features * **build:** add eslint scripts and default configs ([a6abe86](https://github.com/strongloop/loopback-next/commit/a6abe86))
